DESCRIPTION:Research Topic: Unbiased Photo-bioelectrochemical Configuration
  for Formate Production\nAbstract: ** Lecture will be given in English**\n
 \nThe high energy demands and the extensive use of fossil fuels have led t
 o a rising amount of CO2 emissions\, which in turn contribute to the green
 house effect. Thus\, methods that may reuse the emitted CO2 and regenerate
  fuels are needed. Formate Dehydrogenases (FDHs) facilitate the reduction 
 or oxidation of CO2 or formic acid\, respectively. Specifically\, metal-de
 pendent FDH enzymes offer exceptional catalytic performance toward the red
 uction of CO2 into formate.\nThe latter has great potential to be used as 
 fuel in fuel cells or as an H2 carrier that can be liquefied. Toward that\
 , we cloned the gene encoding to the FDH enzyme from the bacteria of Clost
 ridium Carboxidivorans P7 inside pET21a(+) plasmid under T7 promotor and e
 xpressed it in Escherichia coli BL21. Further utilized the enzyme for the 
 development of a bio-electrochemical configuration that can generate forma
 te from CO2. We further integrated the developed FDH-based cathode\nwith a
  photoanode to enable a novel unbiased light-induced CO2-to-formate produc
 tion.\nThe developed configuration couples FDH-based biocathode for formic
  acid bio-fuel production with a solar-driven photoanode for the degradati
 on urea that presents in black water waste. Urea is an abundant nitrogen-c
 ontaining compound that can be found in urine waste. The developed system 
 aims to simultaneously eliminate waste\, minimize CO2 emissions\, and gene
 rate fuels in a one-pot PEC. In my talk\, I will present the different met
 hodologies used\, the results\, and the challenges ahead toward real-world
  applications
